Stems climbing, terete, more than 1 m, stout, ca. 1.5 cm in diam., usually unbranched, internodes 3-4 cm. Leaf blade ligulate or oblong, 7-8 × 1.5-3.3 cm, somewhat unequally obtusely bilobed.

Petals similar to dorsal sepal but smaller, rounded; lip 3-lobed; lateral lobes erect, nearly suborbicular or square, ca. 3 × 4 mm, base with a pair of fleshy, suborbicular calli, apex rounded; mid-lobe ovate, ca. 5 × 2.5 mm, recurved from middle, acute; spur conic, ca. 4 mm. Column ca. 5 mm; stipe ca. 2 mm, ± geniculate-curved at middle. Fl. Apr-Jun. 2n = 38, 114.
